The 4.2V battery pack voltage is fixed for single-cell Li-Ion, while the input supply can go up to 17V, covering most wall adapters and USB-C PD sources. ## Protection set that saves board space Built-in fault protection covers overcurrent, overvoltage, and overtemperature conditions — no external supervisor needed. The only programmable feature is charge current, set by a single resistor to ground. That keeps the BOM lean for high-volume builds. Texas Instruments lists the BQ24170RGYR as Active.","metaTitle":"BQ24170RGYR 4A Li-Ion Charger, 1-3 Cells, 24-VQFN","metaDescription":"Texas Instruments BQ24170RGYR 4A programmable Li-Ion/Polymer charger for 1-3 cells.
